Guaranteed Cost Control of Discrete Time Interconnected Fuzzy Large-Scale Systems With Parametric Uncertainties: An LMI Approach

Guaranteed cost control problem for discrete-time interconnected fuzzy large-scale systems with parametric uncertainties is considered in this paper. DSFGCC (Decentralized States Feedback Guaranteed Cost Controllers) are designed for the uncertain fuzzy large-scale system via LMI technology, which not only ensure asymptotic stability of the closed-loop fuzzy large-scale system, but also minimize the upper bound of a quadratic performance measure. A numerical example is also provided to show the validity of the approach proposed in this paper.
